ILT770 UV Light Meter Instruction Manual 1. INTRODUCTION The ILT770 is a hand held UV meter designed to measure both irradiance in Watts per square centimeter (W/cm²) and dose/exposure in Joules per square centimeter (J/cm²). The system comes configured with one UV sensor and is calibrated as a set (paired meter/sensor). Sensors cannot be swapped from one meter to the other as this will impact the accuracy of the readings.
Units of readout in W/cm² or JW/cm² as shown on display. Date/Time Stamp Numerical Values Graphical Analysis Values (when in Graph mode) Min reading Max reading Average The ILT770 has the ability to apply meta data to the saved results. See Applying meta data in section 10 software. 4 GRAPH MODE The Graph button has four functions (Start Graph, Stop/Review Graph, Data Analysis and Exit) that cycle forward each time button 4 is pressed. It is not possible to return to a previous screen.
3. TAKING A MEASUREMENT The ILT770 sensor is calibrated with the sensor aperture over filled with light perpendicular to the light source. The calibration reference plane is the front surface of the housing. When taking an irradiance or dose measurement the same conditions should be applied. The light source to be measured must fully cover the input optics opening with light. The sensor should be placed so that the front surface is at the treatment location and perpendicular to the source.
conserve battery life. It is possible to graph for longer than 5 minutes when connected to a power source, but it is not possible to save more than 95 datapoints. The bar graph updates every ¼ second offering an easy to evaluate, visual response to changes in intensity over time. The graph can display up to 60 readings (15 seconds) and will begin to scroll forward showing only the most current 60 readings when used for longer duration's.
To recharge the battery, plug the mini USB cable into the slot on the top of the meter. Plug the USB A end of the cable into a PC, USB wall plug, USB power bank or any standard mobile phone USB A charging device. The ILT770 will always turn on when power is supplied via the mini USB. It will take approximately 4 hours to charge the ILT770 when the battery is drained. The meter can be used while charging the battery. Battery replacement cannot be done in the field.
